From 5c7feffd3749ce4b355d0db6334cf39ca94d8d82 Mon Sep 17 00:00:00 2001 From: skal Date: Sun, 15 Feb 2026 23:56:43 +0100 Subject: perf(audio): smooth playback time and RMS-based peak at 60Hz Interpolates audio playback time between callbacks using CLOCK_MONOTONIC for smooth 60Hz updates instead of coarse 8-10Hz steps. Replaces artificial peak decay with true RMS calculation over 50ms window. Ring buffer computes RMS directly on internal buffer without copies for efficiency. All backends updated with get_callback_state() interface for time interpolation. Tests passing (34/34).
